Abstract
The invention relates to a direct-acting type two-position three-way solenoid valve, an inner cavity of which adopts a pressure balancing type sealing structure. The solenoid valve comprises a valve body, valve seats and a valve rod component. The valve body is provided with three ports; a valve disc is fixedly connected with the bottom end of the valve component in the valve body; the bottom end of the valve disc is provided with a through hole which is straight through the valve rod component; the through hole is communicated with an upper cavity channel; when the valve disc falls down, the disc surface of the bottom end of the valve disc can seal a channel port of the valve body, so as to form a sealing structure with communicated valve rods; the medium leads the medium force applied to the valve disc to achieve balance upward and downward by the through hole, so as to form the direct-acting type two-position three-way solenoid valve which adopts the pressure balancing type sealing structure with the communicated valve body. The solenoid valve can work under the condition of vacuum, realize the functions of bearing negative pressure, two-way sealing, random connection and alternation of the ports as an inlet, and work without pressure difference. The solenoid valve can realize direct-acting type control of the solenoid valve with larger diameter in more economic electromagnet range.
Description
Technical field
The present invention relates to the solenoid valve of application in the automation control, particularly relate to a kind of direct-acting type two-position three-way solenoid valve.
Background technique
Solenoid valve is the pipe-line system executive component of control automatically, has two formula actions of switch, and generally solenoid valve is to promote the valve plug to-and-fro motion by transmitting pressure, realizes closing valve or driving valve.Therefore common solenoid valve can only one-way only operation, and promptly MEDIA FLOW according to the rules could realize the function of solenoid valve to use, is applied in usually in the pneumatic control, can not realize water, gas, oily media general.
Summary of the invention
The technical problem to be solved in the present invention, provide a kind of MEDIA FLOW pressure and flow direction of not being subjected to and influence the effect that only is subjected to spring force, gravity and electromagnetic force, thereby reach solenoid valve not by medium differential pressure work, realize that MEDIA FLOW two-wayly all can work to positive and negative, and the direct-acting type two-position three-way solenoid valve that all can work under pressure reduction and the no pressure reduction state is being arranged.
The technological scheme that adopts is:
Direct-acting type two-position three-way solenoid valve adopts the pressure balance type sealing configuration, comprises valve body, valve disc, valve rod assembly.Described valve body is provided with three ports, valve disc is fixedlyed connected with the valve rod assembly bottom in being contained in valve body, the valve disc bottom is provided with the through hole on a straight-through valve rod assembly top, this through hole is connected with last cavity and communicates, fall behind under valve disc, valve disc bottom card can form valve rod communication type sealing configuration with the sealing of valve body internal channel mouth, be issued to balance on the medium power that medium is subjected to valve disc by through hole, solenoid valve is having pressure reduction or is not having the direct-acting type two-position three-way solenoid valve that all can work under the differential pressure conditions.
Advantage of the present invention:
1, adopts the solenoid valve of this kind seal form because when negative pressure, can guarantee normal solenoid valve function, therefore can under the condition of vacuum, work.
2, adopt the solenoid valve of this kind seal form to overthrow the rule that medium needs orientation to circulate, can realize that in two-position three way magnetic valve the arbitrary port of each end interface is as boost port, also can be several ports simultaneously or alternately as boost port, be installed in the system pipeline arbitrarily, all can realize the commutation function of three-way magnetic valve, can also realize solenoid valve by function and distribution function.
3, can realize not having pressure reduction work.
4, can in the electromagnet scope of less expensive, realize the direct-acting type control of larger caliber solenoid valve.
5, change the automatic control that adapter can be used for Chang Kai or normally closed pipeline.
6, be used for the control of water, gas, oily medium.
Description of drawings
Fig. 1 is the structural representation of patent of the present invention.
Embodiment
Direct-acting type two-position three-way solenoid valve adopts the pressure balance type sealing configuration, comprises valve body 1, valve disc 3, valve rod assembly 4.Described valve body 1 is provided with three ports 2,7,8, valve disc 3 is fixedlyed connected with valve rod assembly 4 bottoms in being contained in valve body 1, valve disc 3 bottoms are provided with the through hole 5 on straight-through valve rod assembly 4 tops, this through hole 5 is connected with last cavity 6 and communicates, when 3 times backwardnesss of valve disc, valve disc 3 bottom cards can be with 9 sealings of valve body 1 internal channel mouth, at this moment flowing medium passes through the last cavity 6 of the through hole 5 of valve rod inside to valve, the pressure that acts on the valve rod assembly 4 reaches the balanced type sealing with the pressure that acts on bottom valve disc 3, like this by solenoid valve known iron core deadweight and spring force effect ShiShimonoseki valve; Pick up iron core during energising and drive valve, form the direct-acting type two-position three-way solenoid valve that valve rod is communicated with the pressure balance seal structure.
